Question 1

The pH of soil is raised using:

A	Lime stone
B	None of these
C	Gypsum
D	Urea

Question 1 Explanation:

The pH of soil is raised using lime stone. Limestone (calcium carbonate) is commonly used to raise the pH of acidic soil. It acts as a buffer, neutralizing excess acidity and improving soil fertility.

Question 2

A pencil dipped in water appears bent due to

A	None of these
B	Diffraction
C	Refraction
D	Reflection

Question 2 Explanation:

The correct answer is: C. Refraction Explanation: When a pencil is dipped in water, it appears bent due to refraction. Refraction is the bending of light as it passes from one medium to another of different optical density, such as from air to water. This bending of light causes the pencil to appear displaced or bent at the water's surface.

Question 3

The isotopes of any element contain an equal number of:

A	None of these
B	Protons
C	Neutrons
D	Electrons & protons

Question 3 Explanation:

Isotopes of an element contain an equal number of protons but may have a different number of neutrons. The number of electrons remains the same as the number of protons to maintain the element's neutral charge. Therefore, the correct answer should be "Neutrons" only.

Question 4

Why is a red light used in a traffic signal for danger?

A	Due to high frequency
B	Due to short wavelength
C	It has long wavelength and high frequency
D	It has long wavelength and short frequency

Question 4 Explanation:

Red light is used in a traffic signal for danger because it has a long wavelength and low frequency, making it visible from a distance.

Question 5

One degree of longitude on the equator is equal to a distance of:

A	69 miles
B	60 miles
C	49 miles
D	39 miles

Question 5 Explanation:

At the equator, one degree of longitude corresponds to approximately 69 miles. This value varies slightly depending on the exact shape of the Earth.

Question 6

The heavy water is:

A	Denoted by D₂O and contains deuterium
B	Denoted by D₂O and contains simple hydrogen
C	Denoted by H₂O and contains deuterium
D	Denoted by H₂O and contains simple hydrogen

Question 6 Explanation:

Heavy water is denoted by D₂O and contains deuterium, a heavy isotope of hydrogen. Heavy water, denoted by D₂O, is a form of water where the hydrogen atoms are replaced with deuterium, a heavy isotope of hydrogen containing one proton and one neutron.

Question 7

A cyclone is formed:

A	When moist air rises upward over the ocean
B	When warm, moist air rises upward over the ocean
C	When the warm air rises upward over the ocean
D	When moist air pressed downward over the ocean

Question 7 Explanation:

A cyclone is formed when warm, moist air rises upward over the ocean. Cyclones, also known as hurricanes or typhoons, are formed when warm, moist air rises upward over the ocean’s surface, creating a low-pressure system that can develop into a storm.

Question 8

In fish liver oil, there is/are:

A	Vitamin D only
B	Vitamin A and vitamin E
C	Vitamin A and Vitamin D
D	Vitamin A only

Question 8 Explanation:

Fish liver oil contains both vitamin A and vitamin D, making it a good source of these vitamins.

Question 9

Earthquake is measured by the instrument:

A	Wave guide
B	Hydrometer
C	Seismograph
D	Barometer

Question 9 Explanation:

Earthquake is measured by the instrument called a seismograph.

Question 10

Fishes die outside the water due to:

A	Sun light
B	Carbon monoxide
C	Non-absorption of oxygen
D	Oxygen

Question 10 Explanation:

The option that leads to the death of fishes outside water is "Non-absorption of oxygen". When fishes are out of water, their gills can't extract oxygen from the surrounding air efficiently. As a result, they can't breathe properly, leading to a lack of oxygen in their bodies, which can cause their death. Therefore, the absence or non-absorption of oxygen is what ultimately leads to the death of fishes outside water.

Question 11

What is the total number of combinations of 9 things taken 3 at a time?

A	84
B	48
C	18
D	27

Question 11 Explanation:

The total number of combinations of 9 things taken 3 at a time is calculated using the combination formula, which equals 84. The total number of combinations of n things taken r at a time is calculated using the combination formula: C(n, r) = n! / [r! * (n – r)!]. For this question, it’s C(9, 3) = 9! / [3! * (9 – 3)!] = 84.

Question 12

The protein molecule is made of:

A	Alkaloids
B	Nucleosides
C	Long-range chain of amino acids
D	Short-range chain of amino acids

Question 12 Explanation:

Protein molecules are made up of long-range chains of amino acids. They are large biomolecules made up of long chains of amino acids. These chains fold into complex three-dimensional structures, which determine the protein’s function.

Question 13

The chemical formula for alum is:

A	K₂SO₄ 12 H₂O
B	KAI(SO₄)₃ 8 H₂O
C	None of these
D	KAI(SO₄)₂ 12 H₂O

Question 13 Explanation:

The chemical formula for alum is KAI(SO₄)₂ 12 H₂O.

Question 14

If the radius of a circle is increased three times, then its area is increased:

A	None of these
B	Nine times
C	Three times
D	Six times

Question 14 Explanation:

Area of a Circle - Formula, Area = π × r^2. Therefore, when the radius of a circle is increased three times, its area is increased by a factor of nine. The area of a circle is proportional to the square of its radius. So if the radius is increased three times, the area will be increased by a factor of (3^2) = 9 times.

Question 15

Which of the following contains a greater number of carbon atoms in one mole of each compound?

A	Methanol
B	Chloroform
C	Ethanol
D	Water

Question 15 Explanation:

Chloroform (CHCl3) contains a greater number of carbon atoms in one mole compared to the other compounds listed. In one mole of chloroform, there is one carbon atom, as indicated by the chemical formula CHCl3. Methanol (CH3OH) contains one carbon atom per mole, while water (H2O) and ethanol (C2H5OH) do not contain any carbon atoms. Therefore, chloroform has the highest number of carbon atoms per mole among the given compounds.

Question 16

The ionosphere is located within the thermosphere and extends:

A	None of the above
B	From 50-200 km above the Earth's surface
C	From 60-300 km above the Earth's surface
D	From 50-300 km above the Earth's surface

Question 16 Explanation:

The ionosphere is located within the thermosphere and extends from approximately 60-300 (37 to 190 miles) km above the Earth's surface.

Question 17

Which of the following is used for measuring distance?

A	Farad
B	Curie
C	Light year
D	Coulomb

Question 17 Explanation:

Light year is used for measuring distance. A light-year is a unit of length used in astronomy to measure vast distances in space. It represents the distance that light travels in one year in a vacuum, approximately 9.461 trillion kilometers.

Question 18

When day and night are equal?

A	None of these
B	23 February and 21 September
C	23 March and 21 September
D	21 March and 23 September
